Abstract

SE LAMINA UNA PIEZA EN BRUTO TUBULAR (22) SOBRE UN MANDRIL (14) EN UN LAMINADOR DE PASO DE PEREGRINO. EN UNA PRIMERA FASE DE LAMINACION SE LAMINA UN PRIMER TRAMO DE LA PIEZA EN BRUTO (22) SOBRE UNA PRIMERA PARTE (18, 19) DEL MANDRIL (14), REDUCIENDO EL DIAMETRO EXTERIOR DE LA PIEZA EN BRUTO (22) HASTA EL DIAMETRO EXTERIOR DEL TUBO GUIA Y REDUCIENDO EL ESPESOR DE LA PARED DE LA PIEZA EN BRUTO (22) HASTA UNO DE DOS ESPESORES, UN PRIMER ESPESOR (E1) Y UN SEGUNDO ESPESOR (E2) SUPERIOR AL PRIMER ESPESOR (E1). SE DESPLAZA EL MANDRIL (14) EN SENTIDO AXIAL. SE REALIZA, EN UNA SEGUNDA FASE, LA LAMINACION DE UN SEGUNDO TRAMO DE LA PIEZA EN BRUTO (22) SOBRE UNA SEGUNDA PARTE (20, 21) DEL MANDRIL DISTANCIADA DE LA PRIMERA PARTE EN SENTIDO AXIAL, REDUCIENDO EL DIAMETRO EXTERIOR DE LA PIEZA EN BRUTO HASTA EL DIAMETRO EXTERIOR DEL TUBO GUIA Y REDUCIENDO EL ESPESOR DE LA PARED DE LA PIEZA EN BRUTO (22) HASTA EL OTRO DE LOS DOS ESPESORES, EL PRIMER ESPESOR (E1) Y EL SEGUNDO ESPESOR (E2).ONE PIECE IN TUBULAR GROSS (22) ON A MANDRILE (14) IN A PILGRIM PASSENGER. IN A FIRST PHASE OF LAMINATION A FIRST SECTION OF THE GROSS PART (22) ON A FIRST PART (18, 19) OF THE MANDRILE (14), REDUCING THE EXTERNAL DIAMETER OF THE GROSS PIECE (22) TO THE EXTERNAL DIAMETER OF THE TUBE GUIDE AND REDUCING THE THICKNESS OF THE WALL OF THE PIECE IN GROSS (22) UP TO ONE OF TWO THICKNESSES, A FIRST THICKNESS (E1) AND A SECOND THICKNESS (E2) SUPERIOR TO THE FIRST THICKNESS (E1). THE MANDRILE (14) MOVES IN AXIAL SENSE. THE LAMINATION OF A SECOND SECTION OF THE GROSS PART (22) ON A SECOND PART (20, 21) OF THE DISTANCED MANDREL OF THE FIRST PART IN AXIAL SENSE, REDUCING THE EXTERNAL DIAMETER OF THE PIECE IS CARRIED OUT IN A SECOND PHASE GROSS TO THE EXTERNAL DIAMETER OF THE GUIDE TUBE AND REDUCING THE THICKNESS OF THE WALL OF THE PIECE IN GROSS (22) TO THE OTHER OF THE TWO THICKNESSES, THE FIRST THICKNESS (E1) AND THE SECOND THICKNESS (E2).
